Antibiotic and Probiotic Therapies in the Adjuvant Treatment of the Chronic Periodontitis.
- Conditions
- Chronic Periodontitis Complex
- Interventions
- Registration Number
- NCT03692819
- Lead Sponsor
- Universidade Estadual Paulista Júlio de Mesquita Filho
- Brief Summary
Currently, with the increase of bacterial resistance to antibiotics associated with its side effects, it is necessary to find other adjuncts to combat the disease that are an alternative to the use of antibiotics. The use of probiotics has been proposed in the literature as an adjunct therapy for the treatment of periodontal diseases, however, few controlled and randomized clinical studies have been performed. The objective of this double-blind randomized controlled trial will be to evaluate the response of clinical and microbiological periodontal parameters to the comparison of two different adjuvant therapies (antibiotic and probiotic) for the treatment of stages II and III grade B periodontitis.
- Detailed Description
Currently, with the increase of bacterial resistance to antibiotics associated with its side effects, it is necessary to find other adjuncts to combat the disease that are an alternative to the use of antibiotics. The use of probiotics has been proposed in the literature as an adjunct therapy for the treatment of periodontal diseases, however, few controlled and randomized clinical studies have been performed. The objective of this double-blind randomized controlled trial will be to evaluate the response of clinical and immunological periodontal parameters to the comparison of two different adjuvant therapies (antibiotic and probiotic) for the treatment of stages II and III grade B periodontitis. Patients will be randomized into 3 groups: Group 1 (n=15): periodontal debridement, Group 2 (n=15): periodontal debridement associated with antibiotic (Metronidazole 400 mg + Amoxicillin 500mg) and Group 3 (n=15): periodontal debridement associated with probiotic (Lactobacillus reuteri). Clinical (plaque index, gingival index, probing depth, gingival recession, relative clinical attachment level and periodontal inflamed surface area (PISA) index) and immunological data obtained before and after periodontal therapy (baseline, 30 and 90) will be consolidated and made available on average ± standard deviation and normality tested using the Shapiro-Wilk test. For statistical analysis, the software BioEstat 5.0 (Belém, PA, Brazil) will be used, with p-value \< 0,05.

- Primary Outcome Measures
Name Time Method Probing Depth change Baseline, 30 and 90 days The change in the probing depth will be measure in millimeters before and after the treatment.
- Secondary Outcome Measures
Name Time Method Gingival Recession Baseline, 30 and 90 days Evaluated in milimeters before and after the treatment.
Clinical Attachment Level Baseline, 30 and 90 days Evaluated in milimeters before and after the treatment.
Periodontal Inflamed Surface Area (PISA) Baseline, 30 and 90 days Is calculated from data collected on probing the periodontal pocket and are placed in a table which gives the value of the periodontal inflamed surface area.
Microbiological Parameters Baseline, 30 and 90 days crevicular fluid samples will be analyzed by PCR (real time PCR) for detection and quantification of: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola and Lactobacillus reuteri.
Gingival Index Baseline, 30 and 90 days Number of teeth affected before and after the treatment.
Plaque Index Baseline, 30 and 90 days Number of teeth affected before and after periodontal treatment.
